"The application Digital Performer 9 can't be opened" messag

Post by tunefool »

Yikes, I'm suddenly unable to open DP 9.52. It doesn't open at all. When I try to open it, I get a window that says, "The application Digital Performer 9 can't be opened."

I've tried re-installing DP 9.52. That worked once before when I had this same problem. Now it doesn't work at all. I have Norton anti-virus and have done two quick scans and most of a full one. Nothing comes up.

I also tried to do a full uninstall before reinstalling, based on instructions from MOTU's site. (Found here: https://motu.com/techsupport/technotes/uninstalldp) Got rid of most everything except the last items on their list, except these:

com.motu.DigitalPerformer (folder)
com.motu.DigitalPerformer.plist (file)
com.motu.MotuAudioSystem (folder)

Couldn't find them anywhere.

Help!

Did you try right-clicking and opening it from the pop-up menu instead of double-clicking or COMMAND-O?
